Paper Abstract

CD-ROM has established itself as the preferred medium for the cost-effective distribution of software and various types of multimedia information. The ongoing price reductions of write- once CD-R media and drives are broadening the application range of CD-R from CD- prototyping and small-scale data distribution towards data archiving and bck-up at the desktop. The addition of erasability would increase the attractiveness of recordable CD technology and enable its wide-spread use for personal recording of all types of data files with convenient data interchange. A CD-erasable system (CD-E) with the following characteristics would be very desirable: 1) compatible with existing computer systems and software, 2) erasable with direct overwrite (DOW), 3) recordable using CD-R recorders with minimum modification, 4) readable on CD-ROM players with minimum modification, and 5) reliable. The potential of Ag-In-Sb-Te phase-change materials for CD-E discs and some basic studies have been previously reported by Ricoh. In this paper, we present detailed results of DOW recording on Ricoh's CD-E discs at 2.4-2.8 m/s (CD double speed). We conclude that reliable writing and reading as outlined in the concept above can be achieved with this CD-E system.
